2004 Chevrolet Tahoe LT 4.8L Poor Idle Quality, MIL Lamp on
Posted to GM Driveability on 1/26/2011 12 Replies

Thanks in advance for your help. Please read related history and repairs before replying. This is my bosses truck and we are at a loss. It misses only at idle, runs great going down the road. It is missing mostly on Cyl. #1 and slightly on #8. You can watch it...
